`IMPROVEMENT IN MACHINES FOR SAWING STEEI RAILROAD-RAILSr Specificationforming partof Letters Patent No. l86,42 3, dated January 23, 1877;application filed October 20, 17876.

t to the accompanying drawings, and to the letters of reference markedthereon.

My invention relates to an improvement in machine for cutting steelrailway-rails; and consists of i a table or frame on which is mounted insuitable bearings two adjustable circular saws, holding-wheel, andcarryingchain, which moves upon suitable grooved pulleys or wheels,arranged. and operating with relation to each other, as will hereinaftermore fully appear..

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In theaccompanying drawings, which form part ot' my specification,Figure 1 is a Aside elevation of my improvement. Fig. 2 is an end View.Fig. 3is avertical and longitudinal section. Y s

Manufacturers have found great difficulty in utilizing worn-outrailway-rails when con? structed of Bessemer steel. The peculiar formofthe T-rail which is now-in general use renders the heatin g of them tothe welding or forging point almost impossible. The neck or web of therail, being thinner than the base and head, becomes heated lirst, andbefore the head of the rail is sufficiently heated for being drawn outby the action of the rolls or hammer, the edges of the base and webwaste away by the action of the heat of the lrnace, causing a veryconsiderable loss of material. To avoid this loss and facilitate thereduction of the rail to other forms of merchantable steel is the objectof my invention. I separate the rail into three parts by cutting itlongitudinally by means of circular saws f, arranged upon a suitableaxis, said saws belat the will of the operator.

ing so arranged on the axle that the space between them may be increasedor diminished In conjunction with the saws f is used a pulley-Wheel, j,which is used for holding the rail m down on the way A, which is securedon the table or frame A', the web of the rail m traveling under the theperiphery ot* the `wheel j, as represented in Figs. 2 and 3. The rail mis carried forward to the saws f by means of an endless chain, D, havingcarrying-links c, the projections of which catch against the end of therail m, as shown in Fig. 3. rIhe chain D travels over grooved pulleys orwheels Bfand O. I representsa belt-pulley, h, on the axis ot' thegrooved wheel B, the belt o of which passes around a pulley, k.(Represeu ted by dotted lines in Fig. l.) On the axis of the pulley k isa belt-pulley, g, the belt p ot' which passes around the pulley l on theaxis of the saws jl But I wish it clearly understood that I do notconfine myself to this arrangement of pulleys for operating the severalparts. the pulley h by suitable driving-power, the grooved wheel B willbe revolved, which, through the medium of thel belts o and p, willrevolve the sawsf, and causethe chain D to travel over the groovedwheels B and C, and the carrying-links ewill carry forward the rail m tothe saws f, which will cut the rail longitudinallx into three parts,which can be cut into suitable lengths, heated and rolled with facilityinto the desired forms of barsteel.

Having thus described the nature and object of my invention, what Iclaim as of my invention isl The adjustable saws f, in combination withthe wheel j, way A, and endless chain D, arranged and operating withrelation -to each other substantially as herein described, and for thepurpose set forth. Y
